Extração de dados geoespaciais do Openstreetmap para geração de redes de ruas

Abstract

With technological advance, maps that were represented only on paper, also started to be represented in digital form, allowing the creation of a series of applications, such as traffic routes applications and logistics applications, since digital maps allow the representation of different types of information in one place. This work has implemented a geospatial data import service from OpenStreetMap that creates a road network to be used by the Graphast framework for vehicle routing. To elaborate this paper the data formats provided by OpenStreetMap were analyzed. The OpenStreetMap elements were mapped to graph elements that Graphast uses, then an algorithm was modeled and created to transform the OpenStreetMap data into a graph. To validate the algorithm, a case study was implemented, where some maps of some regions of the world were processed by the algorithm created in this paper and the results were compared to those obtained by using the GraphHopper framework.
